Physicists using the IceCube Neutrino Observatory at the South Pole have detected for the first time mysterious, high-energy neutrinos that originate outside of the Solar System.

“The IceCube Collaboration has announced the observation of 28 extremely high energy events that constitute the first solid evidence for astrophysical neutrinos from outside our Solar System,” said Dr Spencer Klein of Lawrence Berkeley National Laboratory, who is a member of the IceCube Collaboration and co-author of the paper reporting the discovery in the journal Science.
